Background: Benign pyloric stenosis in not uncommon problem. Different treatment modalities can be implemented each has its drawbacks. In this present a new technique of placement of biodegradable oesophageal stent for treating gastric outlet obstruction secondary to benign peptic stricture Method: 23 year old lady had long history of gastric outlet obstruction secondary to pyloric stenosis req...

As in most anuran amphibians, both male and female bullfrogs (Rana catesbeiana) vocalize. Sex differences in vocalizations in the bullfrog may be due to sex differences in the larynx. We examined the laryngeal muscle to determine whether it possessed androgen receptors and whether there were morphological sexual dimorphisms in the larynx. Using a polyclonal antibody and immunocytochemistry, we ...

This study examined the ultrastructural distribution of agranular vesicle-containing nerve (AVN) and granular vesicle-containing nerve (GVN) in cat cerebral blood vessels fixed in KMnO4. The percentages of the AVN and GVN throughout the adventitial layer in the basilar, middle cerebral, and anterior cerebral arteries were 63.4 and 36.7, 53.9 and 46.1, and 60.2 and 39.8, respectively. The AVN in...

PURPOSE To investigate the effects of botulinum toxin type A(botulinum A toxin) on the autonomic and other non-adrenergic, non-cholinergic nerve terminals. METHODS The effects of neurotoxin on twitch contractions evoked by electrical field stimulation (EFS) were studied in isolated rabbit iris sphincter and dilator muscles using isometric tension recording. RESULTS Botulinum A toxin(150 nM)...

The mechanism of the increased stiffness of peripheral vessels in patients with congestive heart failure (CHF) is unknown. It was considered that an increased sodium (Na+) content of peripheral vessels, shown in experimental CHF, might lead to diminished arteriolar dilator capacity. Thus, Na+ retention was induced in six normal volunteers by the daily oral administration of 0.2 mg of fludrocort...

Since Andrew Logan first described the use of an expanding dilator introduced through the left ventricle for the relief of mitral stenosis this method has been widely accepted. The underlying principle is to use a two-bladed dilator, guided into and opened in the stenosed mitral valve, exerting a disruptive force causing separation of the fused commissures of the valve leaflets. This disruptive...

Using stereotaxic procedures, we electrically stimulated specific sites in the hypothalamus and midbrain of anesthetized dogs pretreated with guanethidine and atropine methonitrate. A tract in which stimulation caused noncholinergic dilator responses in the hindlimbs was identified. The course of this trace was different from that subserving cholinergic vasodilation in the hindlimb musculature....

OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross...
